SPECIFICATION forming part of Letters Patent No. 453,469, dated June 2, 1891.

Application filed February 7, 1891. Serial No. 880,604. (No model.)

To all whom it may concerm.

Be it known that I, HORATIO GALE, a citizen of the United States, residing at Albion, county of Calhoun, State of Michigan, have invented a certain new and useful Improvement in Cultivators; andIdeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings,:whioh form a part of this specification.

In the drawings, Figure 1 is a plan view of my invention. Figs. 2, 3, and 4 are the various arrangements that may be made of the different sets of tooth-carrying bars. Fig. 5 is a rear view showing angle of inclination of carrying-bars with ground and the direction of their adjustment.

My invention relates to cultivators; and it consists of the several improvements on a former invention, shown in patent issuedto me June 3, 1890, No. 429,343, for cultivators. In the patent referred to the cultivator-teeth were carried on cross-beams attached at their centers to drawing-beams, said drawing-beams being of tubing or of that form. The crossbeams were adapted to an adjustment around the draw-beam in such a Way as to permit the shovels nearest the corn to be elevated, and the depth of cut of teeth on that side of draw-beam diminished relatively to the outer teeth. In the construction shown in the patent referred to the elevation of the teeth adjacent to the corn was necessarily accompanied with a corresponding depression of the teeth attached to the other end of the same cross-beam, and caused them to make too deep a out.

In this invention I am able'to overcome the difficulties found to exist in the construction heretofore shown by substituting for the centrally-adjusted cross-beams radial tooth-bearing arms.

In the drawings, E represents the drawbeam; H, the radial tooth-carrying arms, to

'which the cultivator-teeth are attached.

These cross-arms are attached to the drawbeam E at one end by passing under the beam, and are secured thereto by means of the clips H, the cross-bars and clips being concaved to fit and clasp the round beam E. By means of this construction I ain'able to adjust each tooth-carrying arm independently and at any angle with the surface of the ground by simply loosening the bolts holding the clips and adjusting it around the beam E. I am able to set the inner arm to fit the inclination of the ground where corn or other crop has been hilled up, While the outer arm can reremain parallel with the ground or elevated at an angle to correspond with the next row.

In the patent referred to the construction was such that all of the teeth on one side of the cultivator were on one beam. This crossbeam was set obliquely across the draw-beam, so that the teeth were one in advance of another successively from center to outside, and dbris that was gathered by the more advanced tooth must pass down before all of the teeth on that side before freeing itself from the cultivator. By the construction shown in Fig. 3 I am able to keep the teeth comparatively free by allowing the dbris to pass between the teeth on arms in the same set. I am also able by the construction shown to increase or decrease the distance between the arms of the same set, as shown in Fig. l, by adjusting the bars on the beam, which is done by loosening the clips and slid ing them along on the beam in either direction. I

Fig. '2 shows another arrangement of the cross beams or radial arms, in which the earth will be worked toward opposite rows.

Fig. 4 shows an arrangement in which the tendency is to work the earth from one set to the next, and all in one direction,

Fig. 3 shows arrangement in which the tendency is to work the earth toward the row cultivated.

In the rear elevation (shown in Fig. 5) the inner sets are shown as elevated to conform to the inclination of hills of corn or other crop. Such an arrangement is used where a shallow cut is desired next to the crop and a deeper out between the rows.

In case it should be desired to construct the dilferent arms to make them interchangeable, so as to provide for all of the forms shown in the several figuresof the drawings, it will be found necessary to attach the teeth to the arms so as to permit of their being reversed, as some of the arrangement of the arms will reverse the teeth.

What I claim is- 1. In a cultivator, the combination, with the beam or beams, of radial tooth-carrying arms, each arm radiating in one direction only, and having a swivel connection allowing them to be independently set at any angle relative to the ground, whereby the teeth on one side of the beam may be elevated or depressed without affecting the cut of those on the opposite side, and devices for holding the radial arms in their adj usted position, substantially as described.

2. In a cultivator, the combination, with the beam or beams, of radial tooth-carrying arms having a swivel connection allowing them to be independently set at any angle relative to the ground, and adapted to be placed at variable distances from one another on said beam or beams, and devices for hold ing the radial arms in this adjusted position relative to one another on said beam or beams and at the desired angle of inclination, substantially as described.

3. In a cultivator, the combination, with the beam or beams, of radial tooth-supportin g arms having a swivel connection allowing them to be set independently at any angle relative to the ground, and adapted to be interchangeable from one beam to the other, and devices for holding the radial arms in their adjusted position, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
